Chapter 1: Overview
1.1 Initial Configuration
This section details how to configure and manage the Gigabit Managed Switch through the Web user interface. This feature
enables administrators to easily access and monitor the entire status of the switch through any one port of the switch. Statuses
which may be monitored include status of the MIBs, activity of each port, status of spanning trees, port aggregation status,
multicast traffic, VLAN and priority status, even illegal access records.
The default values of the Gigabit Managed Switch are listed in the table below:
Table 1-1: Using Web-based management.
IP Address 192.168.1.1
Subnet Mask
255.255.255.0
Default
Username
Password
192.168.1. 254
admin
After the Gigabit Managed Switch has been configured in the interface, you can browse it. For instance, type http://192.168.1.1
in the address row in a browser. You will see the screen in Figure 1-1, requesting your username and password to log in and
authenticate your access.
Figure 1-1. The login screen.
The default username is “admin” and password is empty. For the first use, please enter the default username and
password, then click the <Login> button.
724-746-5500 | blackbox.com
Page 10
LG B110 8A
Chapter 1: Overview
The login process now is completed. In this login menu, you must input the complete username and password respectively: the
Gigabit Managed Switch will not give you a shortcut to username automatically. This may be inconvenient, but it is safer.
The Gigabit Managed Switch supports a simple user management function allowing only one administrator to configure the
system at the same time. If there are two or more users using an administrator’s identity, it will only allow the one who logs in
first to configure the system. The rest of the users, even with an administrator’s identity, can only monitor the system. Those who
have no administrator’s identity can only monitor the system. There is a maximum of three users able to login simultaneously in
the Gigabit Managed Switch.
NOTE: When you log in to the Switch Web Manager, you must first type the Username of the admin. The password must remain
blank at this point, so simply press Enter. When you log in the Gigabit Managed Switch Web UI management, you can use either
an ipv4 or ipv6 log in. To optimize the display, we recommend you use Microsoft® Internet Explorer® 6.0 or higher, Netscape®
V7.1 or higher, or FireFox® V1.00 above and set the resolution 1024x768. The switch supports a neutral Web browser interface.
NOTE: the Gigabit Managed Switch enables the DHCP function, so if you do not have DHCP server to provide IP addresses to the
switch, the switch default IP is 192.168.1.1.
NOTE: If you need to configure the function or parameter, refer to those sections in the User Guide. Or, access the switch and
click the “help“ under the Web GUI, and the switch will open its easy-to-use help content to teach you how to set the parameters, as shown in Figure 1-2.

Chapter 2: System Configuration
Connecting Network Devices
The switch is designed to be connected to 10-, 100-, or 1000-Mbps network cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using optional SFP transceivers.
Twisted-Pair Devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e, or 6 cable
for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections.
Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through
twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
See Section 4.2 of the LGB1108A Quick Start Guide, “Ethernet Cabling,“ for more information on cabling.
CAUTION: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with
RJ-45 connectors that conform to FCC standards.
1.2 Connecting to PCs, Servers, Hubs, and Switches
Step 1: Attach one end of a twisted-pair cable segment to the device's RJ-45 connector.
Step 2. If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a
modular wall outlet that is connected to the wiring closet. (See Section 1.3, “Network Wiring Connections.”) Otherwise,
attach the other end to an available port on the switch. Make sure each twisted-pair cable does not exceed 328 feet
(100 m) in length.
NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise
backpressure jamming signals may degrade overall performance for the segment attached to the hub.
Step 3. As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps) or
amber (100 Mbps) to indicate that the connection is valid.

1.3 Network Wiring Connections
Today, the punchdown block is an integral part of many of the newer equipment racks. It is actually part of the patch panel.
Instructions for making connections in the wiring closet with this type of equipment follows:
Step 1: Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.
Step 2. If not already in place, attach one end of a cable segment to the back of the patch panel where the punchdown block is
located, and the other end to a modular wall outlet.
Step 3. Label the cables to simplify future troubleshooting. See Chapter 6 of the Gigabit Managed Switch Quick Start Guide:
“Labeling Connections.“

Chapter 2: System Configuration
• Daylight Savings Time Set Offset: Daylight savings time is used in some countries. If you select this setting, the unit will
adjust the time, forward or backward in increments of one hour, between the starting date and the ending date that you select.
For example, if you set the daylight savings offset to be 1 hour, when the time reaches the starting time, the system time will be
increased one hour. And when the time reaches the ending time, the system time will be decreased one hour.
The switch supports valid configurable daylight savings times of –5 to +5 hours in one-hour increments. The zero for this
parameter means you will not have to adjust the current time to enact daylight saving. However, remember that if you do set
the unit to observe daylight savings time, you will need to set the starting/ending date as well. If you do not set the start/end
dates, the daylight savings function will not be activated.
Provide the daylight saving time set offset in this space. The offset is given in minutes east of GMT. The valid range is from 1 to
1440 minutes. The default is 60 minutes.
• Daylight Savings Type: Provide the daylight savings type selection. You can select “By Dates” or “Recurring” type for Daylight
saving type.
• From: To configure when daylight savings start date and time, the format is “YYYY-MMDD HH:MM”.
• To: To configure when daylight savings end date and time, the format is “YYYY-MMDD HH:MM”.
NOTE: The under “from” and “to” was displayed what you set on the “From” and “To” field information.

Chapter 2: System Configuration
2.2.2 NTP
NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time (GMT). If you use the NTP
mode and select a built-in NTP time server or manually specify an user-defined NTP server as well as Time Zone, the switch will
sync the time a short time after pressing yjr <Apply> button. Although it synchronizes the time automatically, NTP does not
update the time periodically without user input.
Time Zone is an offset time of GMT. You have to select the time zone first and then perform time sync via NTP because the
switch will combine this time zone offset and the updated NTP time to calculate the local time; otherwise, you will not able to get
the correct time. The switch supports configurable time zones from –12 to +13 step in one-hour increments.
Default Time zone: +8 Hrs.
Web Interface
To configure Time in the Web interface:
1. Click SYSTEM, NTP.
2. Specify the Time parameter in manual parameters.
3. Click Save.
Figure 2-5: The NTP configuration screen.
Parameter Description
• Server 1 to 5: Provide the NTP IPv4 or IPv6 address of this switch. IPv6 address is in 128-bit records represented as eight fields
of up to four hexadecimal digits with a colon separating each field (:). For example, in “fe80::215:c5ff:fe03:4dc7“, the symbol
“::“ is a special syntax that can be used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it
can only appear once. It can also represent a legally valid IPv4 address. For example, “::192.1.2.34“.
• Buttons: These buttons are displayed on the NTP page:
- Save: Click to save changes
- Reset: Click to undo any changes made locally and revert to previously saved values.
2.3 Account
Only an administrator can create, modify, or delete the username and password. An administrator can modify other guest
identities’ passwords without confirming the password, but it is necessary to modify the administrator-equivalent identity. A
Guest-equivalent identity can modify his password only. Please note that you must confirm administrator/guest identity in the field
“Authorization in advance” before configuring the username and password. Only one administrator is permitted to exist and is
unable to be deleted. In addition, up to 4 guest accounts may be created.

from 32 to 126.
• Password (again): To type the password again. You must type the same password again in the field.
• Privilege Level: The privilege level of the user. The range is 1 to 15. A privilege level value of 15 may access all groups, i.e. it is
a privilege level that is granted the full control of the device. For other users, the privilege level should be the same as or greater
than the group privilege level to have the access of that group. By default setting, most groups will have a privilege level 5,
granting read-only access; a privilege level of 10 has the read-write access. For system maintenance (software uploads, factory
defaults and etc.) users will need to have a user privilege level 15. Generally, the privilege level 15 can be used for an administrator account, privilege level 10 for a standard user account and privilege level 5 for a guest account.

2.4 IP (Internet Protocol)
IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an Internet network.
IP is a "best effort" system, which means that no packet of information sent over is ensured to reach its destination in the same
condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is given an Internet
Protocol address, and this IP address is used to identify the device uniquely among all other devices connected to the extended
network.
The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol addresses allowing for in excess of four
billion unique addresses. This number is reduced drastically by the practice of Webmasters taking addresses in large blocks, the
bulk of which remain unused. There is a rather substantial movement to adopt a new version of the Internet Protocol, IPv6, which
would have 128-bits Internet Protocol addresses. This number can be represented roughly by a three with thirty-nine zeroes after
it. However, IPv4 is still the protocol of choice for most of the Internet.
2.4.1 IP v4
The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually configure an address, you need to
change the switch's default settings to values that are compatible with your network. You may also need to a establish a default
gateway between the switch and management stations that exist on another network segment.
Configure the switch-managed IP information on this page.
The Configured column is used to view or change the IP configuration.
The Current column is used to show the active IP configuration.
Web Interface
To configure an IP address in the Web interface:
1. Click System, IP Configuration.
2. Specify the IPv4 settings, and enable DNS proxy service if required.
3. Click Save.
